Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (5.31%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
The web console for Mimosa B5, B5c, and C5x firmware through 2.8.0.2 allows authenticated command injection in the Throughput, WANStats, PhyStats, and QosStats API classes. An attacker with access to a web console account may execute operating system commands on affected devices by sending crafted POST requests to the affected endpoints (/core/api/calls/Throughput.php, /core/api/calls/WANStats.php, /core/api/calls/PhyStats.php, /core/api/calls/QosStats.php). This results in the complete takeover of the vulnerable device. This vulnerability does not occur in the older 1.5.x firmware versions.
